Practical Applications
## Physics in Nature
Physics isn’t just for labs—it's everywhere in nature! From falling apples to rainbows, the laws of physics explain how the universe works.
## Natural Phenomena Explained
- **Rainbows:** Created when sunlight bends and splits in water droplets.
- **Gravity:** Keeps planets in orbit and lets us walk on Earth.
- **Ecosystems:** Plants use sunlight (energy) and water (matter) to grow.
## Why This Helps
Understanding physics helps us appreciate the beauty of nature and protect our planet.
Examples
- Birds glide using the physics of air resistance and lift.
- Lightning is a giant spark caused by electric fields in clouds.
